Patent JP-H053005-A (JP)
Title: Light-emitting element
Inventor: NISHII YOSHIYUKI
IPC: H01J31/15
Filed: 1991-06-24
Abstract: PURPOSE:To provide a uniform color balance by making different the opening diameters of electron passage sections in a control grid in accordance with the light emitting efficiency of the fluorescent surface. CONSTITUTION:The electron passage section of a control grid 82A constituting a grid electrode group 8A is bored with a large number of meshes which are radially projected substantially with the same diameter toward the side of a fluorescent display section 5, whereby dome-shaped mesh sections 91A, 92A and 93A are integrally formed. As compared with the opening diameter of the mesh 93A corresponding to a fluorescent surface 5R, the opening diameter of the mesh 92A of a fluorescent surface 5B is large and the opening diameter of the mesh 91A of a fluorescent surface 5G is made small. With this construction, when substantially the same control voltages are applied to the control grids 81A, 82A, and 83A, the amount of the electron beam passing through the meshes 91A, 92A, and 93A can be controlled corresponding to the emitted light brightness of each fluorescent surface 5G, 5B, and 5R. This makes it possible to obtain a uniform color balance.

Title: Method and device for controlling speed
Inventor: KUNUUDO BUROOMU
IPC: B26D5/32
Filed: 1989-07-10
Abstract: PURPOSE: To vary the speed so that a body reaches a specific speed and a specific position even when the speed difference and/or load varies by providing a compensation period which depends upon the speed between the generation of a release signal and the start of the speed variation. CONSTITUTION: So that a beltlike film 1 can be braked in proper timing through a tension roller 5 and a clutch brake means 7, a sensor 3 having detected a mark display 2 sends a stop signal and the braking is started. Then when a counter reaches zero, the counter is set to a value Nf and counts down until the tension roller 5 stops; and a pulse generator 8 sends pulses as many as Ns during the count-down time and the difference between two values Nf and Ns , i.e., value Nk represents the length of the compensation period. Thus, the compensation period is made into a variable meeting different speed and load conditions of the body, so even if the speed difference and/or load of the body varies, the body can be controlled so as to reach a specific speed at a specific position.

Inventor: NAITOU HIROMITSU
IPC: C23G1/19
Filed: 1980-12-16
Abstract: PURPOSE:To continuously anneal a cold-rolled steel plate and clean the surface of the steel plate at the same time by quickly cooling a steel plate with oxidized film, having a specific thickness, heated and soaked in a weak by oxidative or nonreductive atmosphere, with an aqueous solution of an alkali metal compound. CONSTITUTION:In the continuous annealing of a cold-rolled steel plate, involving heating, soaking, and cooling processes at least, the steel plate is heated by either direct heating or radiation in a weak by oxidative or nonreductive atmosphere and then subjected to a soaking treatment to form oxidized film of a thickness of 1,000 Angstrom  or less on the surface of the steel plate. Then, steel plate is quickly cooled with a cooling medium composed of an aqueous solution containing one or more of alkali metal compounds, e.g., NaOH, KOH, LiCl, etc. Thus, since the needs for after treatment apparatus for removing oxidized film, reheating zone, overaging treatment zone, final cooling zone, etc., can be eliminated, continuous annealing treatment can be applied to the steel plate at low cost.
